SPECIFICATION forming part of Letters Patent No. 299,750, dated June 3, 1884.

Application filed September 24, 1883. (No model.)

Cliff, county of Summit, Colorado, have invented a new and-Improved Snow-Plow, of which the following is a full, clear, and exact description.

My invention relates to the class of snowplows having a wheel with an annular groove in each side, into which the snow is gathered,

.to be carried around to the upper side and then forced out lateraly by dischargers supported in the grooves; and the invention now consists of slides of gates arranged to close the grooves behind the snow in the grooves to hold it thereon until carried to the upper side, said slides also being arranged to draw into the hub or central portion of the wheel to pass the dischargers; and the invention also consists of a flaring arrangement of the outside rim of the wheel to facilitate the discharge of the snow by said dischargers, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the principal parts of my improved machine. Fig. 2 is a sectional elevation .on the line w x of Fig. l; and Fig. 3 is a detail, mostly in plan view, showing the arrangement of the dischargers.

The large wheel or drum a, having an annular groove, b, in each side, is mounted in the strong supporting-arms 0, extending forward of the track-frame d, to be revolved on its shaft 6 by chains or other belts'on the pulleys f, to gather the snow into the grooves b by the shovels g, which force it through the openings h inside of the rim t, to be carried up in the wheel to the dischargersj,which throw the snow out to the sides of the track. I have found in the use of such machines that the snow is liable to slide down the insides of the rims i and clog the openings h, so as to prevent the machine from working properly. I have therefore arranged the sliding gates 76 to slide out from the central hub or drum of the wheel just in advance of the opening h, to stop the sliding back of the snow and make sure of its be- 5o ing carried up, and to operate these gates so that they will operate at the proper time, and

I will also draw in at the top to pass underthe dischargersj. I have attached them to a yoke, Z, which works on eccentric cams m, attached to the frame, so that while the gates and the yoke revolve around the eccentric with the wheel, the gates will be projected below and withdrawn at the top. I use the yoke instead of eccentric straps to avoid vibrating the gates, also the connecting-joints that would be necg flare from the middle of the wheel outward, to make the grooves widest at the outer edge to facilitate the discharge of the snow from the grooves. The snow is gathered on the curved mold-board a as the machine moves along the track, and is shoveled or scraped therefrom into the wheel-grooves by the shovels y when they pass down the mold-board. The scrapers also gather up the snow to some extent in front of the mold-board.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The stop-gates 7c, in combination with a wheel having annular side grooves, b, shovels g, and dischargers j, said stop-gates being arranged for and provided with means to cause them to project at the lower partof the wheel to stop the snow in the grooves and withdraw at the upper part to pass the dischargers, substantially as described.

2. The stop-gates k, the yoke Z, and the stationary eccentrics m, in combination with a wheel having annular side grooves, b, shovels g, and dischargers j, said stop-gates being arranged to project at.the lower part of the wheel JOHN Q. DAY.

essary with that arrangement. I also propose in this case to have the rim 1' and the shovels' to stop the snow in'the grooves and to with-
